In non-ionic compounds, the two primary sources of intermolecular forces are permanent dipoles and temporary dipoles. Explain what causes each of these types of dipoles to form.
What do these results tell us about the difference in molecular mass between the aroma molecules and the colour molecules? In the lab there were both an 80C and a 100C distillate
A sample of hydgrogen gas, H2, has a volume of 8.56L at a temperature 0C and a pressure of 1.5 atm. Assuming the gas behaves ideally: how many moles of H2 are present in this gas sample
The hydrogen gas generated is collected over water at 25.0°C. The volume of the gas is 535 mL measured at 1.00 atm. Calculate the number of grams of sodium used in the reaction. (Vapor pressure of water at 25°C = 0.0313 atm.)
At 745K, the reaction 2AB(g) ? A2(g) + B2(g) has a Kc = 2.00 x 10-2. If a mixture of 1.00 mol AB and 1.00 mol A2 is sealed into a 10.0 L flask and heated to 745K, what will be the equilibrium concentration of B2
If a process is carried out at constant pressure P and the volume V of the system decreases, then V is (negative, positive) and the work w is (negative, positive, zero).
Determine the structure of compound U. Be sure to include a concise discussion of the reasoning. Construct tables summarizing the IR and 1H NMR data, and assign the peaks in the IR and NMR spectra to the appropriate structural elements in U. Expla..
Find out the formula of the gas produced if Na 3 P(s) sodium phosphide, is reacted with H 2 O
What maximum mass of carbon dioxide is produced by the complete combustion of 10.0 kg of this fuel?
Twenty grams of a solute are added to 100g of water at 25C. the vapor pressure of pure water is 23.76 mmHg, the vapor pressure of the solution is 22.41 torr.
At 710.mm hg a sample of nitrogen gas occiuped 625 ml.what volume does gas occupy if the temperature remains constant and the pressure increases to760.mm hg?
The enthalopy of cumbustion benzoic acid C6H5COOh is commonly used as the standered for calibrating constant volume bomb calorimeters.
